More schema updates.  Three new objects.

Product is a top-level content name, e.g. 'rhel' or 'fedora'.

Products can have many ProductVersions.  Some versions are 'test' versions
(e.g. 6.90).  This needed as the path to fedora-test-6.90 looks like
fedora/linux/core/test/6.90/ while the path to fedora-core-6 looks
like fedora/linux/core/6/ (the extra 'test' indirection there...)

Category is meant to be able to capture the standard directory
structure for 'core', 'extras', 'updates', 'updates-testing', 'test',
and 'epel' cleanly.  It uses $VERSION and $ARCH in the path names to
be replaced when creating a Content.

Content refers to the combination of a Category, a ProductVersion, and
an Arch, and is still the highest level unit of data that can be synced.
These have names like fedora-core-6-i386. (product, category, version, arch).

The other objects are unchanged fundamentally.
Your comments would be appreciated.
